Task 7: Plan for the Fiber-Optic Cables
Table 3-11 on page 3-17 describes the required fiber-optic cables.
Table 3-11. Type and Length of Cables Required for Clustering
Fiber-Optic
Cable Type
Maximum Distance
Supported Connects From: Connects To:
SMF with SC to
LC connectors
(NonStop
S-series servers
only)
Up to 80 meters
Because of the hardware
implementation of the
ServerNet protocol in the
links between a cluster
switch and each node,
this distance is less than
the distance that SMF
can support.

the type of zone-to-zone connections you use. For details, see Appendix G, Using the Long-
Distance Option.
